Solution: In deep sea diving, nitrogen is dissolved in the bloodstream...


In deep sea diving, nitrogen is dissolved in the bloodstream under the high pressure. This leads to the condition known as “the bends.” Actually, nitrogen is much more soluble in fatty tissue than it is aqueous solutions (e.g. blood), and the nitrogen dissolved in the brain at a higher pressure can be a great concern for divers.


The Henry’s law constant for N2(g) in fatty tissue is around 2 x 10-3 mol/L•atm at 25°C (as opposed to 6.8 x 10-4 mol/L•atm in water at that same temperature). Calculate the concentration of N2(g) in fatty tissue if the air pressure is 2.5 atm (that would correspond to a depth of about 50 feet). Remember the air is roughly 79% nitrogen.
